Parafoveal or peripheral vision is important for various everyday activities. This is particularly relevant to those who suffer from visual field defects. Here we quantified the effect of visual crowding, normal aging, and glaucoma on the spatial extent of the functional field of view (FFV) under divided attention.

Unlike visual acuity measured by single-letter recognition or visual perimetry measured by light spot detection, we measured the FFV using a target letter presented either alone or in letter triplets appearing across the visual field. A subject's task was to report whether the target letter was the same as the letter displayed concurrently at the central fixation region (i.e., divided attention task). Over the trials, a plot of the proportion correct for letter recognition versus target location was constructed, resulting in a visual field map.

The results obtained from three subject groups-normal young adults, normal older adults, and patients with glaucoma-showed that on average the central 20° visual field was relatively robust to uncrowded target recognition under divided attention. However, the FFV shrunk down to the central 10° visual field when the target appeared in clutter, suggesting a strong crowding effect on FFV. An additional shrinkage of the FFV occurred in the presence of aging and glaucoma.

Using a quantitative method, we demonstrate that crowding, aging, and glaucoma independently decrease the spatial extent of FFV under divided attention and that crowding seems to be the major contributor limiting FFV.

Our FFV test may complement standard clinical measurements by providing functionally relevant visual field information.

Pulmonary clots are seen frequently on chest computed tomography performed after trauma, but recent studies suggest that pulmonary thrombosis (PT) and pulmonary embolism (PE) after trauma are independent clinical events.

To assess whether posttraumatic PT represents a distinct clinical entity associated with the nature of the injury, different from the traditional venous thromboembolic paradigm of deep venous thrombosis (DVT) and PE.

This prospective, observational, multicenter cohort study was conducted by the Consortium of Leaders in the Study of Traumatic Thromboembolism (CLOTT) study group. The study was conducted at 17 US level I trauma centers during a 2-year period (January 1, 2018, to December 31, 2020). Consecutive patients 18 to 40 years of age admitted for a minimum of 48 hours with at least 1 previously defined trauma-associated venous thromboembolism (VTE) risk factor were followed up until discharge or 30 days.

Investigational imaging, prophylactic measures used, and treatment of clots.
or chest injury with an Abbreviated Injury Score >3; P = .04) and major venous injury (23 [82.1%] without major venous injury and 5 [17.9%] with major venous injury; P = .02). No deaths were attributed to PT or PE.

To our knowledge, this CLOTT study is the largest prospective investigation in the world that focuses on posttraumatic PT. The study suggests that most pulmonary clots are not embolic but rather result from inflammation, endothelial injury, and the hypercoagulable state caused by the injury itself.

Mammals, in contrast, can maintain stable body temperatures, and their ventricular repolarization is strongly modulated by changes in heart rate and by sympathetic nervous system activity. The aim of this study was to assess the role of body temperature, heart rate, and circulating catecholamines on local repolarization gradients in the ectothermic ball python (Python regius). We recorded body-surface electrocardiograms and performed open-chest high-resolution epicardial mapping while increasing body temperature in five pythons, in all of which there was a change in T-wave polarity. However, the vector of repolarization differed between individuals, and only a subset of leads revealed T-wave polarity change. RNA sequencing revealed regional differences related to adrenergic signaling. In one denervated and Ringer's solution-perfused heart, heating and elevated heart rates did not induce change in T-wave polarity, whereas noradrenaline did. Accordingly, electrocardiograms in eight awake pythons receiving intra-arterial infusion of the β-adrenergic receptor agonists adrenaline and isoproterenol revealed T-wave inversion in most individuals. Conversely, blocking the β-adrenergic receptors using propranolol prevented T-wave change during heating. Our findings indicate that changes in ventricular repolarization in ball pythons are caused by increased tone of the sympathetic nervous system, not by changes in temperature. Therefore, ventricular repolarization in both pythons and mammals is modulated by evolutionary conserved mechanisms involving catecholaminergic stimulation.
There is a lack of evidence regarding the effectiveness and safety of pharmacologic venous thromboembolism (VTE) prophylaxis among patients who undergo neurosurgical interventions for traumatic brain injury (TBI).

To measure the association between timing of VTE prophylaxis after urgent neurosurgical intervention for TBI and thromboembolic and intracranial complications.

This retrospective cohort study included adult patients (aged ≥16 years) who underwent urgent neurosurgical interventions (craniotomy/craniectomy or intracranial monitor/drain insertion within 24 hours after admission) for TBI at level 1 and 2 trauma centers participating in the American College of Surgeons Trauma Quality Improvement Program between January 1, 2012, and December 31, 2016. click here Data were analyzed from January to August 2020.

Timing of pharmacologic VTE prophylaxis initiation after urgent neurosurgical intervention (prophylaxis delay) measured in days (24-hour periods).

The primary outcome was VTE (deep vein thrombosis or neurosurgical interventions for TBI, early pharmacologic VTE prophylaxis was associated with reduced risk of thromboembolism. However, earlier initiation of prophylaxis was associated with increased risk of repeated neurosurgery. These findings suggest that although timely initiation of prophylaxis should be prioritized, caution should be used particularly during the first 3 days after the index procedure, when this risk appears to be highest.The inhibitor of store-operated Ca2+ entry (SOCE) BTP2 was reported to inhibit ryanodine receptor Ca2+ leak and electrically evoked Ca2+ release from the sarcoplasmic reticulum when introduced into mechanically skinned muscle fibers. However, it is unclear how effects of intracellular application of a highly lipophilic drug like BTP2 on Ca2+ release during excitation-contraction (EC) coupling compare with extracellular exposure in intact muscle fibers. Here, we address this question by quantifying the effect of short- and long-term exposure to 10 and 20 µM BTP2 on the magnitude and kinetics of electrically evoked Ca2+ release in intact mouse flexor digitorum brevis muscle fibers. Our results demonstrate that neither the magnitude nor the kinetics of electrically evoked Ca2+ release evoked during repetitive electrical stimulation were altered by brief exposure (2 min) to either BTP2 concentration. However, BTP2 did reduce the magnitude of electrically evoked Ca2+ release in intact fibers when applied extracellularly for a prolonged period of time (30 min at 10 µM or 10 min at 20 µM), consistent with slow diffusion of the lipophilic drug across the plasma membrane. Together, these results indicate that the time course and impact of BTP2 on Ca2+ release during EC coupling in skeletal muscle depends strongly on whether the drug is applied intracellularly or extracellularly. Further, these results demonstrate that electrically evoked Ca2+ release in intact muscle fibers is unaltered by extracellular application of 10 µM BTP2 for less then 25 min, validating this use to assess the role of SOCE in the absence of an effect on EC coupling.
Clinical trials have neither focused on early intervention for psychosocial impairment nor on the contribution of components of borderline personality disorder (BPD) treatment beyond individual psychotherapy.

To evaluate the effectiveness of 3 early interventions for BPD of differing complexity.

This single-blinded randomized clinical trial recruited young people between March 17, 2011, and September 30, 2015, into parallel groups. The study took place at 2 government-funded mental health services for young people in Melbourne, Australia. Inclusion criteria were age 15 to 25 years (inclusive), recent DSM-IV-TR BPD diagnosis, and never receiving evidence-based BPD treatment. A total of 139 participants were randomized (pool of 876; 70 declined, 667 excluded), balanced for sex, age, and depressive symptomatology. Data analysis completed May 2020.

Subsyndromal hypomanic symptoms are relatively common in the general population and are linked to the onset of bipolar disorder. Little is known about their etiology and whether this is shared with the etiology of bipolar disorder or other mental illnesses.

To examine the genetic and environmental architecture of hypomanic symptoms in a nonclinical youth sample and compare estimates at varying severity levels and their association with diagnosed bipolar disorder.

This cohort study used phenotypic and genetic data from the Child and Adolescent Twin Study in Sweden and included individuals with International Statistical Classification of Diseases and Related Health Problems, Tenth Revision diagnosis of psychiatric disorders from national registries for residents of Sweden. Associations between hypomania and polygenic risk scores for bipolar disorder, major depressive disorder and schizophrenia were also investigated. Analysis began November 2018 and ended October 2021.

Hypomanic symptoms were assessed using the parent-rated Mood Disorders Questionnaire when the twins were aged 18 years.
